An estimate of carbon footprint of Ekurhuleni Health District office and provincial clinic employees

Climate change is regarded as the greatest threat facing the world today. The Intergovernmental Panel on Climate Change (IPCC) concluded that climate change is caused by human activities, as a result of greenhouse gases (GHGs) being emitted into the atmosphere. Scientific literature on the impact of climate change is well documented, especially for the health sector. The mission of the Gauteng Department of Health (GDoH) is to “contribute towards the reduction of the burden of diseases in all the communities in Gauteng”. Ekurhuleni Health District is part of GDoH and shares a similar mission. However, this mission is under threat due to the direct and indirect impact of climate change on the public health sector. Therefore, it is essential for Ekurhuleni Health District and Provincial Clinics to take measures to reduce their contribution to climate change in the light of improving the health of their constituent. This study estimates the carbon footprint of the employees of Ekurhuleni Health District and Provincial Clinics and determines the knowledge and perception of climate change among managers and operational employees. The methodologies of the Greenhouse Gas Protocol (GHGP) and the Department of Environmental Forestry and Rural Affairs (DEFRA) were used to quantify the carbon footprints of the employees of the Ekurhuleni Health District and Provincial Clinics. A content analysis was applied to determine the knowledge and perception of climate change. The study revealed that Scope 2, indirect emissions (electricity), accounts for 92% (35150 t CO2e) of the total carbon footprints for the period of five years, 2010-2014. Scope 1, direct emission (vehicles), is responsible for 4% (1362 t CO2e) and Scope 3, indirect emissions for ICT, for 2% (862 t CO2e), office paper 1% (181 t CO2e) and air conditioners 1% (458 t CO2e). The majority of employees demonstrated basic knowledge of climate change. However, the concept of GHGs was unfamiliar to most of the employees. In terms of perceptions of climate change, the majority of employees were concerned about the future of the planet and climate change and believed that climate change will impact their job description. The study recommends the following mitigation measures, among others, to reduce carbon footprints: (1) electrical vehicles; (2) substituting personal desktops with laptops; and (3) substituting HFC-23 air conditioner refrigerant with R410A. These recommendations have the potential to reduce the carbon emissions by 2445 t CO2e for the period of five (5) years and save R7 875 089 from fuel and power consumption. Furthermore, the District Office and Provincial Clinics can generate a revenue of R293 400 by registering for a CMD project for five years or R1 173 600 for the duration of the project (20 years).Environmental SciencesM.
